Well, just like not all men what to do the exact same thing with their lives, so not all women want to do the exact same things with their's. Some women find fulfillment in being a CEO of a huge company or a doctor and some women fine fulfillment in staying home taking care of their families. I don't thinkk it has to do with the treat of sexual harassment or stress, it mostly has to do with what she place value on.
In our culture it's very much expected from men to work hard and make a lot of money and being successful. However it's very much expected that women work hard, be successful, make a lot of money AND take care of the kids, clean the house, take care of her husband while looking wonderful all the time. Women are basically expected to have 2 full time jobs - at work and as a home maker.
I personally know 2 women who left very profitable positions to stay home and take care of the kids, and I also know of one guy who's doing that while his wife is finishing her masters degree and working to support the family. I think that if you take off the social expectancies of the traditional male-female roles, there are people in both gender who are more into working outside of the house and people who are more into working in the house.
I think that in order to make this work in a couple \ a family situation, both man and woman needs to understand and treat what the home maker's job as what is it - a job, and not as a comfortable situation for a lazy person. In most cases, being a home makes is working around the clock and coordinating a pretty complicated work environment as well as being relax in many stressful situations and having a very wide range of knowledge and proficiencies.
It's easy to look down on a homemaker job because we tend to measure success with money and that job doesn't pay anything. However if a couple decide on this lifestyle it's very important to find other way to measure and appreciate the homemaker's job.
Finally - In the early to probably mid 80's feminist agenda,going out to work was the right thing to do while staying home was an abomination and a non feminist way of life. Today, feminist groups are working to insure freedom of choice to women as individuals which means that if a woman wants to stay home and be a housewife it's a valid choice from a feminist perspective.
